I am trying to write a formula field that would display one address line if only Address Line One has value assigned in the database and  two address lines if both address lines have values.

Here is the code I am using but it does not display the 2nd address:

dim x as string
if len({CWVMembers.Addr2})>3 then
    x = trim({CWVMembers.Addr1}) + Chr(13)+ {CWVMembers.Addr2}
elseif isnull({CWVMembers.Addr2}) = true then
    x = trim({CWVMembers.Addr1})
else
    x = trim({CWVMembers.Addr1})
end if
formula = x

Please advise whatI need to do to correct this.

stringVar varAddress1:=trim("aaaaaaaaaaa");
stringVar varAddress2:=chr(0);

if varAddress2=chr(0)  then
 varAddress2:=""
else
 varAddress2:=trim(varAddress2);

if len(varAddress2)>0 then
  varAddress2:=chr(13) + varAddress2;

varAddress1 + varAddress2;

If  field can be NULL then you need to test for the NULL condition first

dim x as string
if isnull({CWVMembers.Addr2}) = true then
    x = trim({CWVMembers.Addr1})
else
    x = trim({CWVMembers.Addr1}) + Chr(13)+ {CWVMembers.Addr2}
end if
formula = x

using fields from your datasource definition

stringVar varAddress1:={CWVMembers.Addr1} ;
stringVar varAddress2:={CWVMembers.Addr2};

if varAddress2=chr(0)  then
 varAddress2:=""
else
 varAddress2:=trim(varAddress2);

if len(varAddress2)>0 then
  varAddress2:=chr(13) + varAddress2;

varAddress1 + varAddress2;

If the field can be NULL the only test that will succeed on it is IsNull.  All other tests will fail and the formula will terminate execution.  In Crystal NULL is lack of a value not the empty string or the chr(0) string.

mlmcc is correct about needing to test for nulls first, but he left your length > 3 test out of his formula.  You could combine the IsNull and length tests (to simplify the formula slightly).

dim x as string
if isnull({CWVMembers.Addr2}) or len({CWVMembers.Addr2})<=3 then
    x = trim({CWVMembers.Addr1})
else
    x = trim({CWVMembers.Addr1}) + Chr(13)+ {CWVMembers.Addr2}
end if
formula = x
